Question details
The user is unable to save highlights, annotations, and other edits made to PDF documents.

- Product
- PDF Reader / Editor
- Device & OS
- not provided
- Scenario
- Reviewing, editing, and annotating PDF files for personal or professional use.
- Observed behavior
- Changes such as highlights and annotations fail to save, resulting in the loss of all edits once the PDF file is closed.
Before attempting any fixes, try using the 'Save As' option to save a copy of the PDF directly to a local folder like your Desktop to rule out temporary location or permission restrictions.
Remove Read-Only Restrictions from the PDF
Ensure the PDF file isn't set to read-only, which intrinsically prevents any new edits or highlights from being saved to the document.
A common reason for saving failures is that the file is locked by the operating system. Removing this attribute allows your PDF reader to write new changes.
Right-click the problematic PDF file and select 'Properties' on Windows, or 'Get Info' on macOS.
Uncheck the 'Read-only' attribute box (Windows) or ensure sharing and permissions are set to 'Read & Write' (Mac).
Click 'Apply' and 'OK', then reopen the document, apply a new highlight, and attempt to save again.

Verify Device Storage Space and File Location
Edits cannot be saved if your device's storage is full, or if the file is located in a restricted cloud-synced folder.
Update Your PDF Editor Application
Outdated software versions can harbor bugs that prevent the proper saving of PDF annotations.

Frequently Asked Questions
Why are my PDF highlights disappearing immediately after I close the file?
This usually happens if the PDF file is marked as read-only, if you lack write permissions for the folder where the file is stored, or if you close the document without explicitly saving the changes using Ctrl+S or the Save button.
Can I recover PDF edits or highlights that didn't save?
Unfortunately, if the edits were not saved successfully and the program was closed, the annotations are typically lost. To prevent this, manually save your work frequently or use the 'Save As' function to create version backups.
How do I save a highlighted PDF as an entirely new file?
To save your highlighted PDF as a separate document, go to the 'File' menu, choose 'Save As', select a new destination folder on your local drive, assign the file a new name, and click 'Save'.
Does WPS Office support saving PDF highlights natively?
Yes, WPS Office features comprehensive native PDF editing capabilities. You can seamlessly apply highlights, add annotations, and save the file directly without needing extra plugins or experiencing third-party save errors.
